Parkinson's disease is a progressive neurological disorder that affects movement and motor control. It impacts nearly 1 million people in the United States alone. The condition manifests through various symptoms and can significantly alter a person's quality of life.
Understanding Parkinson's Disease
Parkinson's disease results from the loss of dopamine-producing brain cells in the substantia nigra. This region plays a crucial role in controlling movement. As these cells die, dopamine levels decrease, leading to the characteristic symptoms of the disease.
The exact cause of Parkinson's remains unknown, but researchers believe it involves a combination of genetic and environmental factors. Age is a significant risk factor, with most cases diagnosed after age 60.
Parkinson's is typically diagnosed through clinical examination and medical history. There is no definitive test for the condition, making early detection challenging.
Symptoms and Movement Disorders
The primary symptoms of Parkinson's disease involve movement disorders. These include:
Tremors: Involuntary shaking, often starting in the hands or fingers
Bradykinesia: Slowed movement and difficulty initiating motion
Rigidity: Stiffness of muscles and reduced range of motion
Postural instability: Impaired balance and coordination
Non-motor symptoms can also occur, such as:
Cognitive changes
Sleep disorders
Depression and anxiety
Loss of smell
As the disease progresses, symptoms typically worsen, and new ones may emerge. This can lead to significant disability and reduced independence.
